Abstract
A hardware specification of an active reconfigurable intelligent surface (aRIS), which possesses the capability to mitigate the adverse multiplicative fading effect in non-line-of-sight communication systems employing a reflective antenna, is investigated. Based on its detailed link budget analysis, the salient characteristic and operational insight of an aRIS are discussed. For a specific example of an aRIS-assisted single-user single-input single output wireless communication system operating at millimeter-wave frequencies, a requirement of the aRIS hardware is determined, including noise figure, gain, power and linearity, under both normal and weak path loss condi-tions. Discussion on performance trade-off is also given.
